AP2331 Single-Channel USB Switch

AP2331 Single-Channel USB Switch

The AP2331 from Diodes Incorporated is a single-channel, current-limited, integrated high-side power switch optimized for hot-swap applications. The devices have fast short-circuit response time for improved overall system robustness and provide a complete protection solution for application subject to heavy capacitive loads and the prospect of short circuit. It offers reverse-current blocking, over-current, over-temperature and short-circuit protection, as well as controlled rise time and under-voltage lockout functionality.

The device is available in SOT23, SC59 and U-DFN2020-3 packages.
